Removal
► Remove the side covers (see 4.2.29.1 "Removing the Side Covers" [}57]).
► Dismantle the base unit.
► Divide the base unit into upper and lower parts.
► Unplug all connectors from the LDU-X controller (see 4.2.29.3 "Removing and Dismantling the
LDU Basis" [}58]).
► Loosen the 6 screws (1) fastening the
LDU-X control board and remove the
board.
Installation
► Installation is performed by following the above instructions in the reverse order.
► Restore the press-fit connections for the LDU-X control board.
► Fit the LDU base unit back together.
► Re-install the LDU base unit (see 4.2.29.9 "Assembling and Fitting the LDU Basis" [}63]).
► Fit the side covers (see 4.2.29.10 "Fitting the Side Covers" [}65]).
CAUTION
Important installation instructions
► Whenever you dismantle the base unit, you will need to level the LDU-X out again on
the machine (see operating instructions)!
CAUTION
Updating software
If the control board was replaced, you need to check whether the latest firmware version is
installed.
► Switch the LDU-X on.
► Go to the service menu to view the firmware version programmed.
► Check whether there is a more recent firmware version in the Software Download
Center (SDC) (www.siplace.com). You may want to download the new firmware from
the Software Download Center and transfer this to the control board.
If you have no access to the SDC, contact the SIPLACE hotline.

Removal
► Remove the side covers (see 4.2.29.1 "Removing the Side Covers" [}57]).
► Remove and dismantle the base unit, separating it into top and bottom sections and unplug all
press-fit connections to the LDU-X control board (see 4.2.29.3 "Removing and Dismantling the
LDU Basis" [}58]).
► Dismantle the base plate of the upper section of the base unit (see 4.2.29.4 "Removing the
Base Plate" [}60]).
► Dismantle the motor mounting plate (see 4.2.29.5 "Removing the Motor Mount" [}60]).
► Loosen the 8 grub screws on the
couplings(2) (2 screws for each coup-
ling side).
► Carefully pull out the motors with the
motor shafts(1).
► Follow the same procedure for the
other side of the couplings and pull
the couplings off the shafts(3).

40 Service Manual SIPLACE LDU-X Linear Dipping Unit 11/2017
Installation
► Carefully push the couplings off the shafts(3).
► Before assembly, align the shafts(3) and the
couplings so that the flattened sides of the
shafts(3) and the corresponding grub screw(2)
on the coupling point in the same direction.
► Fix the coupling onto the shafts(3), by tightening
the corresponding grub screws.
► Carefully push the motors and motor shafts(1)
together into the couplings. Make sure that the
flattened sides of the motor shafts and the cor-
responding grub screw (2) on the coupling point
in the same direction.
NOTICE!
A reliable connection is only formed if one of the
grub screws touches the flattened side of the
motor shaft!
.
► Align the motors and couplings so that there is a
gap of around 1 mm between the coupling and
the motor mount.
► Tighten the grub screws. Make sure that the set
gap does not change during tightening.
CAUTION!
Make sure that the coupling does not grate
against the sides!
.
► Refit the motor fixing plate (see4.2.29.6 "Fitting the Motor Mount" [}61]).
► Refit the base plate (see 4.2.29.7 "Fitting the Base Plate" [}61]).
► Restore the press-fit connections for the LDU-X control board, reassemble and refit the LDU
base (see 4.2.29.9 "Assembling and Fitting the LDU Basis" [}63]).
► Fit the side covers (see 4.2.29.10 "Fitting the Side Covers" [}65]).
CAUTION
Important installation instructions
► Whenever you loosen the couplings, you will need to remeasure the positions of the
axes.
► Whenever you dismantle the base unit, you will need to level the LDU-X out again on
the machine (see operating instructions)!
